Abstract

A quantum cascade laser (QCL) operating at 2.5 THz has been used for gas phase spectroscopy and as local oscillator in a heterodyne receiver. The linewidth and frequency tunability of the QCL have been investigated by either mixing modes of the QCL or by mixing the emission from the QCL with the emission from a 2.5 THz gas laser. The frequency tunability as well as the linewidth are sufficient for Doppler limited spectroscopy of methanol. Noise. temperature measurements with a hot electron bolometer and a QCL yielded the same result as with a gas laser as local oscillator.
